3 <p>Roman numerals are a way of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols we use. Roman numerals are used in royal titles, book names, sequences, and more. Here we will be discussing Roman numerals, rules, and examples.</p>

4 <h2>What is 843 in Roman Numerals?</h2>

5 <p>The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed the names and wondered what these<a>symbols</a>(I, II) represented?</p>

6 <p>Those are Roman numerals. Earlier people used to count using fingers, sticks, bones, etc. When life became complex, a<a>standard form</a>was required to count. Ancient Romans used the Roman numeral system to count. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count.</p>

7 <p>In Roman numerals, we use DCCCXLIII to represent 843. Here, D is 500, CCC is 300 (100 each), XL is 40, and III is 3. Let’s learn more about Roman numerals and how we write them.</p>

8 <h2>Basic Rules for 843 in Roman Numerals</h2>

9 <p>There are certain basic rules to write a<a>number</a>in Roman numerals. In this section, let’s discuss some basic rules that need to be remembered when writing a number in Roman numerals.</p>

10 <h3>Rule 1: Addition Method</h3>

11 <p>The<a>addition</a>method is used when the smaller number is placed after the larger number.</p>

12 <p>For example, DCCCXLIII → D + CCC + XL + III → 500 + 300 + 40 + 3 = 843</p>

13 <h3>Rule 2: Repetition Method</h3>

14 <p>To write a large number, certain Roman numerals can be repeated up to three times. CCC → 300 (C repeated three times).</p>

15 <h3>Rule 3: Subtraction Method</h3>

16 <p>If a smaller number is placed before a larger number in Roman numerals, we subtract the smaller number from the larger number. For example, XL → 50 - 10 = 40</p>

17 <h3>Rule 4: Limitation Rule</h3>

18 <p>The symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated.</p>

19 <p>For example, we won't write VV for 10; instead, we use X, and 40 is written as XL, not XXXX.</p>

50 <p>To find the number of coins per artifact, divide the total coins by the number of artifacts: DCCCXLIII = 843 IIII = 4 843 / 4 = 210.75, but since coins are whole units, use the integer part. 210 in Roman numerals can be written as CCX.</p>

67 <p>First, calculate the total number of apples given to customers:</p>

69 <p>XXXIII = 33</p>

68 <p>XXXIII = 33</p>

70 <p>VIII = 8 33 × 8 = 264</p>
